BACKGROUND: Physical exercise can be part of treatment in patients with chronic fatigue syndrome (CFS), where the aim would be to improve strength and endurance through increasing physical exercise (intensity and time) without aggravating symptomatology. The present study examines the effectiveness of a reconditioning programme (focusing on strength, endurance, balance and propioception) for achieving maximum functional capacity according to the clinical status of CFS patients. METHODS: Sixty-eight patients with CFS were randomly assigned to two groups: a control group (CG) comprising 22 patients and an active group (AG) of 46 patients, the latter being invited to take part in a functional reconditioning programme based on 12 weeks of laboratory training followed by a further 12-week home training period...

BACKGROUND: Evidence of the benefit on propioceptive neuromuscular facilitation for reducing falls in older people does not exist. OBJECTIVE: The aim of this study is to evaluate the effects of propioceptive facilitation over falls and biomechanical variables, in comparison to standard treatment and control groups. MATERIALS AND METHODS: Series cases comparative for the 24 participants were recruited and randomnly assigned to 3 groups. Group 1, propioceptive neuromuscular facilitation, group 2, standard treatment, and 3 control...

According to the scientific reports the postural stability is inseparably associated with hearing organ's correct functioning. The aim of the study was to evaluate the degree of disorders occurring in balance reactions in this group of children with profound hearing loss compared to their healthy peers. The study worked with a total of 228 children, including 65 who are deaf (DCH) and 163 subjects without any hearing deficits (CON) in the control group. Stabilometric measurements were performed with the use of a force distribution platform...

Two wild fledgling kestrels exhibited lack of motor coordination, postural reaction deficits, and abnormal propioception. At necropsy, the cerebellum and brainstem were markedly underdeveloped. Microscopically, there was Purkinje cells heterotopy, abnormal circuitry, and hypoplasia with defective foliation. Heterotopic neurons were identified as immature Purkinje cells by their size, location, immunoreactivity for calbindin D-28 K, and ultrastructural features. The authors suggest that this cerebellar abnormality was likely due to a disruption of molecular mechanisms that dictate Purkinje cell migration, placement, and maturation in early embryonic development...

INTRODUCTION: we report the clinical, radiological and pathological features of a spinal pleomorphic xanthoastrocytoma, an unusual neoplastic entity in a really rare location, establish an appropriated management of these lesions and review the short available english literature. CASE REPORT: a 60 years old woman consulted with doctor because she felt progressive clumsiness accompanied by occasional paresthesias on her left hand. Neurological examination showed up weakness and slight propioceptive disturbances...

Several studies have found that Parkinson's disease (PD) disrupts the organization of complex motor sequences regardless of the influence of parkinsonian medications. A clear candidate for the neural bases of such deficits, which we term "coordinative," is the failure to integrate propioceptive and visual information by cortico-striatal circuits in a timed fashion. Recent reports, however, have indicated that deep-brain stimulation of the subthalamic nucleus (STN DBS) may result in an improvement in coordinative deficits beyond the amelioration of "intensive deficits" such as bradykinesia and scaling errors...

An experiment was carried out with humans as subjects, aged between 7 and 53, in which a conditional discrimination procedure with compound samples made up by exteroceptive (colored geometric shapes) and proprioceptive stimuli (different ways of pointing at them) was used. Thus, subjects were trained to perform differently in the presence of each sample, and later to choose the correct comparison. They were then evaluated in a conditional discrimination with unitary samples for each one of the components of the previous compound stimulus (only behavior and only colored shapes)...

BACKGROUND: Stochastic resonance is a nonlinear phenomenon whereby the addition of noise can improve the detection of weak stimuli. An optimal amount of added noise results in the maximum enhancement, whereas further increases in noise intensity only degrade detection or information content. The phenomenon does not occur in linear systems, where the addition of noise to either the system or the stimulus only degrades the signal quality. Stochastic Resonance (SR) has been extensively studied in different physical systems...

Peripheral nerves consist of 3 layers with differing characteristics: the endoneurium, perineurium, and epineurium. The perineurium represents a continuum with the pia-arachnoid from the central nervous system and extends distally with the sheath of capsular cells of peripheral sensorial organs and propioceptive receptors. It is made of layers of flattened cells surrounded by a basement membrane and collagen fibers, forming concentrically laminated structures around single nerve fascicles. Functionally, the perineurium modulates external stretching forces (that could be potentially harmful for nerve fibers), and along with endoneurial vessels, forms the blood-nerve barrier...

BACKGROUND: A number of studies have shown that proprioception training can reduce the risk of injuries in pivoting sports, but the mechanism is not clearly understood. AIM: To determine the contributing effects of propioception on knee joint position sense among team handball players. STUDY DESIGN: Prospective cohort study. METHODS: Two professional female handball teams were followed prospectively for the 2005-6 season...

A 4-month-old female Holstein Friesian calf was referred to the Veterinary Teaching Hospital, University of Berne, Switzerland for evaluation of ataxia, weakness, apathy and stunted growth. Clinical examination revealed generalized ataxia, propioceptive deficits, decreased menace response and sensibility. Postmortem examination did not reveal macroscopic changes of major organs. Histologically, the brain and the spinal cord lesions were characterized by polymicrocavitation, preferentially affecting the white matter fibers at the junction of grey and white matter and by the presence of Alzheimer type II cells...

INTRODUCTION: Ballism is a rare movement disorder that presents with violent and wide amplitude flinging movements of the limbs, mainly caused by injury in the contralateral subthalamic nucleus or its afferent or efferent connections. CLINICAL CASE: We describe the case of a 50-year old male who had ballistic movements after a cervical trauma. He subsequently developed choreoathetoid movements and a distonic attitude in the left upper limb later. A C2-C3 sensory level and proprioceptive loss in this limb were the main findings in the examination...

Neuropathic arthropathies is a destructive and deforming joint process related to a disruption of propioceptive and nocioceptive innervation. Growth factors, neurological and vascular factors might be involved. Diabetes, alcoholic neuropathy or syringomyelia appear as the most common causes. We report the case of a 61-year-old woman affected by syringomyelia, with a neuropathic arthropathy of the shoulder. Differential diagnosis includes neurological diseases, septic arthritis, tumours and other destructive arthropathies such as aseptic nechrosis, chronic osteomyelitis, synovial chondromatosis, metabolic diseases (gout, chondrocalcinosis) or repetitive haemarthrosis in haemophilia...

The role of the cerebellum in schizophrenia has been highlighted by Andreasen's hypothesis of "cognitive dysmetria," which suggests a general dyscoordination of sensorimotor and mental processes. Studies in schizophrenic patients have brought observations supporting a cerebellar impairment: high prevalence of neurological soft signs, dyscoordination, abnormal posture and propioception, impaired eyeblink conditioning, impaired adaptation of the vestibular-ocular reflex or procedural learning tests, and lastly functional neuroimaging studies correlating poor cognitive performances with abnormal cerebellar activations...

BACKGROUND: Low level connective tissue inflammation has been proposed to play a role in thyroid associated ophthalmopathy (TAO). The aim of this study was to investigate this postulate by a musculoskeletal approach together with biochemical parameters. METHODS: 13 patients with TAO and 16 controls were examined. Erythrocyte levels of Zn, Cu, Ca2+, Mg, and Fe were determined. The musculoskeletal evaluation included observational data on body posture with emphasis on the orbit-head region...

In Experiment 1, 10 pigeons were exposed to a successive symbolic matching-to-sample procedure in which the sample was generated by the pigeons' own behavior. Each trial began with both response keys illuminated white, one being the "correct" key and the other the "incorrect" key. The pigeons had no way of discriminating which key was correct and which incorrect, since these roles were assigned on a random basis with the same probability of 0.5 for each key. A fixed ratio of five responses was required on the correct key...

Dysmorphophobia, also known as Body Dysmorphic Disorder (BDD), can become a serious illness that results in severe complications such as social isolation, self-mutilations, suicide attempts, and even suicide. Many authors currently include BDD among the spectrum of obsessive-compulsive disorders. There are two distinguishable variants of BDD: psychotic and non-psychotic. The current trend considers these variants as one same disorder characterized by an insight spectrum. However, the psychotic variant exhibits more severe symptoms...

STUDY DESIGN: Case report. OBJECTIVES: To present an interesting case of a 14-year-old male with acute paresis of upper extremities and progressive difficulty with lower extremities. The patient is a competitive wrestler and was performing his daily abdominal workout 'sit-ups' with hands interlocked behind his head. During the end and immediately following his abdominal workout, he felt progressive weakness in his upper extremities. He was rushed to the hospital within an hour and seen in the emergency room and admitted to the neurology service for a presumed thromboembolic event...
